Title: Quantum Sensing Based on Diamond Nitrogen Vacancy Centers

Bio: Dr. Laraoui’s primary research focuses on developing new quantum materials based on color centers in diamond (NV, SiV, GeV), and defects in wide-bandgap semiconductors (SiC, GaN, ZnO) and two dimensional materials (hBN, TMDs) for applications in quantum sensing and quantum information processing. His current research follow four main directions:

• Quantum sensing: nanoscale magnetic, current, and temperature mapping of condensed matter phenomena; far-field imaging of single transition metal nanoparticles (size < 20 nm).

• Defect discovery and spectroscopy in two dimensional materials and wide bandgap semiconductors: studying the spin and optical properties of the defects, developing new quantum devices based on their performances. 

• Quantum computing: exploring magnetic, optical, and mechanical cavities for coupling distant spin-qubits for scalable quantum networks

• Hybrid photonics based on coupling single color centers to metamaterials for optical networks.

These research activities are mainly experimental and involve spectroscopy (optical detected magnetic resonance, fluorescence, magneto-optics), microscopy (TEM, AFM, SEM, Near-field, Confocal, Far-field, etc.), RF/MW electronics (PCB and stripline design, RF/MW equipment and pulse control), materials processing (ion beam implantation, irradiation, high temperature annealing, acid clearing, etc.), and device fabrication (E-beam, Evaporation, etching, etc.).
